Inflatable Food Carrier Case

ABSTRACT

An inflatable food carrier case formed of flexible plastics material has an outer wall and inner wall to create an inflatable air chamber there between. Upon inflation of the air chamber the case provides protection for the enclosed item(s) of food, such as fruit. There may be a semi-rigid rim to provide structure to the body of the case. The case is formed in two halves and joined together via a hinge. Air inlets/outlets are provided across the hinge to allow air to flow into other air chambers. A valve is provided in the outer wall for inflation. An attachment device is provided for a clip or similar device to enable attachment to another article.

FIELD OF THE INVENTION

The present invention relates to an inflatable carrier case for carrying either singular or multiple units of fruit and other items of food and relates particularly, though not exclusively, to such a carrier case for children's lunches.

BACKGROUND TO THE INVENTION

Current means of carrying food or fruit are hard plastic containers, soft lunch boxes, cling film or other means. These are either cumbersome or do not provide a good level of, or adequate, protection. For example, there is a tendency for a piece of fruit to become bruised as it bounces around inside a hard lunchbox or if it is left loose in a school bag or briefcase.

The present invention was developed with a view to providing a food carrier case with inflatable walls which overcomes or substantially ameliorates the above disadvantages and/or more generally to provide a protective food/fruit carrier case of improved performance.

References to prior art in this specification are provided for illustrative purposes only and are not to be taken as an admission that such prior art is part of the common general knowledge in Australia or elsewhere.

SUMMARY OF THE INVENTION

According to the present invention there is provided an inflatable food carrier case comprising walls formed of a flexible airtight material, wherein the walls are formed at least partly of an outer and inner wall to create an inflatable air chamber which, when inflated, provides protection for the food within the carrier case.

Typically the walls of the carrier case are made of a flexible plastics material. The carrier case may have an extra outer wall made of other material such as, but not exclusively, a fabric material. The inner and outer walls may be of different shape and size (to suit the contents it is designed to hold) and to reflect various outer appearances. For example the overall exterior appearance of the item may be that of a head with a face on it, a rugby ball or football or an animal so as to appeal to children.

Part of the structure may be a rim which can be made from a more rigid substance to provide structural shaping to the case where necessary. For inflation the case may include a valve in the inner or outer wall. A hinge where air can move between different parts of the case may be used in a “clamshell” overall design, enabling the user to deploy an opening where articles can be inserted/retrieved into/from the receiving space.

The case may be formed with a single cavity adapted to receive an item of food therein. Alternatively, the case may be formed with a plurality of cavities adapted to receive respective multiple items of food therein.

The case can be closed and secured by means of any suitable fastening mechanism, for example a burr fastener, sliding clasp fastener or another form of fastening. The fastening may be covered by a flap to provide a neat outward appearance.

Preferably there is also provided a further fastening device such as a clip and/or strap to enable the case to be attached to another object such as bag, belt, bike, car.

One or both of the inner wall or the outer wall may be adapted to receive a coolant or coolant device such as a freezer gel.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

A first embodiment of an inflatable food/fruit carrier case 10, as depicted schematically in the FIGS. 1 to 3 of the accompanying drawings, is preferably formed of plastics materials such as PVC or other food contact-safe materials. The plastics material might be opaque or light-transmissive or translucent or transparent. The carrier case 10 comprises an outer wall 11 a and an inner wall 11 b arranged to form an inflatable air chamber which, when inflated, provides protection for the food within the carrier case. Walls 11 a and 11 b are typically plastics-welded onto another specially formulated rim or structure 12. A semi-rigid material may be inserted inside the rim or structure 12 to provide a degree of structural rigidity to the rim or body of the case 10.

The walls 11 may be made in different shapes and sizes to suit the object(s) and for individual design. In this embodiment, the walls 11 of the case 10 are designed to accommodate a single piece of fruit, for example, an apple or an orange (not shown). The case 10 comprises two halves 13 a and 13 b joined together by a hinge 16. Each half 13 includes an inflatable air chamber which is configured to form a hemispherical internal cavity. Preferably the inflatable chambers in the respective halves 13 a and 13 b are in fluid communication via air inlets/outlets extending across the hinge 16, to allow air to flow between the air chambers.

As shown in FIG. 1, a flap 14 is provided around the top half 13 a to facilitate closure of the case 10 and to provide a neat finish. The flap 14 is closed or secured by means of hook and loop fastener 15 or another form of fastening

A hook, loop, clasp or similar device 17 is fixed to the top half 13 a of the case 10, and attached thereto is a clip, hook or strap 17 a or other means of attachment to enable the case 10 to be secured to a bag, belt or other object.

Air can be blown into the air chambers formed between the inner and outer walls via a valve 18 to create an air cushion around the piece of fruit.

In use, a piece of fruit (not shown) is inserted into the cavity formed in the lower half 13 b of the case 10, preferably while it is in a semi-inflated condition as shown in FIG. 2. The carrier case 10 is then closed by bringing the top half 13 a over the top of the piece of fruit, and the securing it to the lower half 13 b by means of flap 14 and the hook and loop fastener 15. One then blows air into the air chambers via the air valve 18 to create a secure fit around the enclosed piece of fruit.

The inflatable food/fruit carrier case 10 can be carried loose, placed directly into a school bag or other carrying device, or secured by way of a hook, clip, or strap 17 a or other means to a bag, belt, bike, dashboard or other object. The piece of fruit can be safely carried in the case 10 without being bruised or otherwise spoiled in transit. After use the case 10 can be deflated for ease of transportation and storage.

A second embodiment of an inflatable food/fruit carrier case 20 is depicted schematically in the FIGS. 4 and 5 of the accompanying drawings. This embodiment is made from similar materials to the first embodiment and is specifically designed to carry a banana 22 therein. The carrier case 20 comprises an outer wall 24 a and an inner wall 24 b arranged to form an inflatable air chamber which, when inflated, provides protection for the food within the carrier case. Walls 24 a and 24 b are typically plastics-welded onto another specially formulated rim or structure 26. A semi-rigid material may be inserted inside the rim or structure 26 to provide a degree of structural rigidity to the rim or body of the case 20, however this is optional.

The case 20 comprises two halves 28 a and 28 b joined together by a hinge 30. Each half 28 includes an inflatable air chamber which is configured to form a banana-shaped internal cavity. Preferably the inflatable chambers in the respective halves 28 a and 28 b are in fluid communication via air inlets/outlets extending across the hinge 30, to allow air to flow between the air chambers. A valve 32 is provided to allow the air chambers to be inflated.
